995. Bonnett, R.K. and H.W. Hulbert. 1922. Sweet clover. Id Agr. Expt. Sta. Circular #22.
More drought tolerant than red clover or alfalfa; biennial white is best for Idaho; value for hay and soil improvement; white yields 1T more hay than yellow; quality of hay better from yellow; well adapted to alkali soils; 15 lb/ac seeding; early seeding best, without nurse crop in drier areas; peas are best nurse crop; as a green manure, is expensive, decay is slow, depletes soil moisture; need to summerfallow after SC in the drier areas.
2784. Hulbert, H.W.. 1927. Sweetclover.. ID Agr. Expt. Sta. Bull. #147.
Biennial white is best forage, biennial yellow is too short; can handle alkaline soils; earlier seeding is best; 15 lb/ac seed, or 10 lb/ac in drier areas; nurse crop is risky, peas may be best; 3/4 T/ac hay first season, 2-3 T/ac second year; best used for pasture and soil improvement; can be grazed early spring through fall; improves soil quality, breaks up subsoil; sweetclover as green manure too expensive for dry areas; one system used is WW/SC planted in fall (unscarified seed) at 5 lb/ac; after wheat harvest, pastured SC into late fall; field is spring plowed and SF; then WW again, this raised WW yields 3-8 bu/ac; might try with Hubam (annual) SC.

Better sweetclover stands when seeded alone or with grass; peas better than cereals; hi (>10 lb/ac) seeding rate leads to better stands; best seeding date April 10-May 7; more weeds in second year when grown with companion crop; sweetclover/grass mix gave greater wheat yield increase than SC alone, also had less erosion; excellent thorough study.
